Introduction

Lateral drains and sewers that serve two

or more properties, and connect to the

UK public sewerage network, are now the

responsibility of the relevant Water and

Sewerage Company [WASC].

See Figs.1 and 2 for typical layouts

according to the principles of Sewers for

Adoption 7th edition [SfA7].

For regulations and typical details specifically

applicable to Inspection Chambers in

adoptable applications, see pages 4-5.

Non-adoptable drainageDrains that only serve individual properties

remain the responsibility of each house-

holder. These are still subject to Building

Regulations Part H1, see page 4.

Transportation If chambers are carried on vehicles with

a flat bed, ensure that:

l The bed is free from nails and other

projections.

l Chambers are adequately secured.

HandlingRange 600 polypropylene chambers are

lighter than other, more traditional materials,

yet have excellent strength and impact

Transportation, handling and storage

characteristics. So they are easier to

handle and less likely to be damaged.

However, to minimise risk of damage:

l Load/unload chambers by hand:

avoid use of mechanical handling

equipment if possible.

l If mechanical equipment employed,

use special hoist equipment with

textile straps. Do NOT use metal

hooks or chains.

l Do not drop chambers onto hard

surfaces or drag them along the

ground.

StorageStore chambers on level ground that

is free of stones and sharp objects.

Exercise reasonable care to avoid

damage prior to their installation.

Installation Guidance

NOTE: The following is a summary of

installation procedures following selection of

a suitable Range 600 Base for the required

number of inlets.

Excavationl Take precautions against trench collapse:

support trench sides deeper than 1.2m.

Preparationl Prepare and compact 100mm regulating

bed of granular material in trench bottom.

Positioning/connectionl Position Base on regulating bed. Check

outlet is facing in the correct direction: i.e.

with side inlets swept to follow water flow.

l Ensure all inlets/outlet are free from dirt

or grit.

l Use standard jointing sequence

to connect 150mm, 225mm or 300mm

UltraRib pipes to inlets/outlet.

For connection of TwinWall pipes in these

sizes, use Adaptors 6TW145, 9TW145 or

12TW145

If connecting to 150mm, 225mm or

300mm Hepworth Clay, insert the

appropriate adaptors into the required

inlet/outlet as follows:

– 150mm Clay use Adaptor TA/2



NOTE: The main through channel MUST

be used. Bends up to 45° may be used on

any inlet or outlet.

Backfilll Using same material as bedding,

backfill around Base in 150mm layers

up to underside of shaft socket.

Ensure inside of Base is free of debris.

Preparing shaftl Cut corrugated shaft to approx. Invert

depth of Chamber.

RECOMMENDATION: leave extra 300mm

depth to allow for possible final site changes.

l Locate sealing ring between 2nd and 3rd

ribs from shaft bottom. Ensure ring is

seated correctly/not twisted.

l Clean inside of Base socket and lubricate

this entire area.

l Position shaft at 45° angle into Base

socket. Vertically push home manually or,

if required, with mechanical assistance

(if so, protect top of shaft).

Backfill trenchl Before starting backfill, cover top of shaft

to prevent ingress of dirt or grit.

Trafficked application (e.g. roadway)l Follow Highway Specification: use

Type 1 or similar backfill, and compact.

Non-trafficked application (e.g. garden area)l Use “as-dug” material (excluding stones

>40mm dia., frozen or vegetable matter) in

300mm layers. Tamp mechanically around

full circumference of Base so that current

conditions re ground and water table, and

anticipated future loading, can be

supported.

RECOMMENDED SPD LEVELS:

– Green areas 90%

– Paved areas/limited traffic load 95%

– Roads/heavy traffic loads 98%

l Avoid knocking shaft during backfilling –

and keep free of debris.

l Backfill to formation level.

Trim shaft/fit restriction access cap l Trim shaft to required height using fine-

toothed saw.

NOTE: If finished ground level is not yet

known, leave shaft proud of surface and

keep open end covered until final completion.

l When shaft trimmed to final height, locate

sealing ring between 2nd and 3rd ribs from

shaft top. Ensure ring is seated correctly/not

twisted.

l Lubricate inside of 350mm restrictor cap,

position over top of shaft, and push fully

home.



Car Surface




600mm dia Shaft






Use the appropriate Cover and Frame to

suit application area/function:

A15 – non-loaded green/landscaped areas

only accessible to pedestrians and bicycles

B125 – paved areas with limited traffic load,

where heavy vehicles do not have access

D400 – roads with heavy duty traffic loads

Galvanised cover and framesGalvanised options are recommended for

A15 applications.

For A15 applications in areas such as

domestic gardens and/or applications

subject to occasional/temporary loading

up to 15kN (1.5 tonnes) such as domestic

driveways, the frame should always be

supported by a concrete plinth. (See Fig. 5).

Ductile iron covers and framesDuctile iron options are recommended for

heavier loaded applications:

Class B125 - with medium duty loading

capacity of 125kN (12.5 tonnes) where the

frame is supported by a concrete plinth.

Suitable for applications such as car parks

and service roads.

Class D400 classification - with loading

capability of up to 400kN (40 tonnes) where

supported by a concrete plinth. Suitable for

carriageways and roads subject to motor

vehicle trafficking.

l Trim shaft section at last stage of

construction. Ensure unit is at correct

height.

l Protect shaft from traffic loading by

shuttering its external ribs.

l Lay 150mm thick slab of pre-cast or in

situ concrete around top of shaft chamber

with minimum opening 750mm x 750mm

– or 750mm diameter – to ensure that any

loads are distributed away from the shaft.

l On top of slab, construct Class B

engineering brickwork OR concrete blocks

OR pre-cast concrete seating rings up to

required height.

l According to required loading application,

position the appropriate Cover and Frame

on top of slab. (See Fig.6)

Fig.6. Installation detail for B125 loading: paved areas with limited traffic load; and for

D400 loading: roads with heavy traffic loads




A chamber which has substantially different

invert levels will require backdrop connection

of one or more drains. This operation can

be done externally on site. (See Fig.7)

Use a combination of Backdrop Kit [NE950

or NE960], with associated 100/110mm or

150/160mm fittings, for in situ connection to

a 600 shaft, as follows:

l Drill required opening into corrugated

shaft section at appropriate place

l Clean and remove any swarf from the

opening

Fig.7. Installation detail – typical backdrop situation

Installation guidance: backdrop connections


Driveway




600mm dia Shaft




l Install the special 110mm or 160mm seal

into the opening

l Fully lubricate around the entire internal

surface of the seal

l Insert specially designed “in-situ” socket

connector into the seal opening

l Lubricate the outside surface of the spigot

pipe to be connected and insert into the

socket connector

l Make remaining connections in the same

way as for standard jointing of 110mm or

160mm pipes and or fittings

Installation of backdrop connections




All testing of these non-man entry

chambers and connecting pipework must

be undertaken at ground level.

For guidance, please use the following:

Air Testing using remote test bags: equipment requiredl 3 x 1 metre x 8mm Steel Drainage Rods

l 50mm Double Worm Screw for use with

Steel Drainage Rods

l PVC sealing bags fitted with Schrader

Valve and 6 metre hose.

l Steel drain plug with testing point

l Bicycle Pump

l Tyre pressure gauge to ensure correct

inflation pressure of the test bags.

Air Testing procedure1. Assemble drain rods to 3 metres in length

with double worm attachment on end.

2. Remove as much air as possible from the

PVC Sealing Bag.

Method: hold valve open and squeeze

bag flat.

Tip: folding the bag in half to make it

as small as possible will make it easier

to locate.

3. Twist neck of PVC Sealing Bag into

double worm attachment until it has

firm grip on bag.

4. Ensure valve end of hose is secure with

no danger of falling down the chamber.

5. Hold drain rods and hose from the PVC

Sealing Bag together. Start to lower the

test bag into the base.

Tip: Keep hose tight while lowering bag.

This helps to keep bag in place.

6. When bag is in chamber base, position it

into the channel of the run to be tested.

7. By using the channel as a guide, slide test

bag into the mouth of the pipe, and as far

as possible into the pipe.

Method: use rods to push bag into

position.

8. Leave rods attached (this ensures bag is

held in position). Start to pump the bag

up using a bicycle pump.

NOTE: When inflating the test bags, follow manufacturer’s instructions to ensure pressure is not exceeded. Use tyre pressure valve to monitor bag pressure.

9. If required, remove rods by twisting them

in an anti-clockwise direction to release

the double worm. Check the valve end

of hose is safely positioned.

Testing

MaintenanceAs with all Wavin Chambers, the smooth

interior bore of chamber channels and

associated pipe systems will aid the flow

of water and waste through the system.

Because man-entry of Wavin chambers

is not possible, maintenance work

such as Rodding, Jetting and CCTV

inspection must be undertaken at

ground level.

Always follow the Health & Safety and

Operational procedures of equipment

suppliers.

10. Place a similar sealing bag or a steel

drain plug at the other end of the pipe

length to be tested.

(This could be another chamber or a

terminal access point.) Both bag and

steel drain plug must include a suitable

testing point.

11. Attach a manometer. Carry out required

air test method.

12. Remove sealing bag

Method: twist double worm attachment

around the hose at ground level. Lower

it down the hose, guiding the rods to the

bottom of the chamber and once again

grip the bag.

NOTE: No requirement to grip bag

tightly. This is simply to aid its removal.

Release as much air as possible from

bag. Then slide bag back out the pipe

with the rods.

When this is done, lift/remove all test

equipment out of the chamber.
